Shells break on pillars in SSL, among other super steep slopes (related to collision changes probably)

[gheskett]

This behavior does not match vanilla and should either be fixed or have a means of toggleability. This is probably(?) not an issue directly related to exposed ceilings, as the SSL pillars do not seem to have any collision underneath them.

The bug is reproducible in vanilla, but might still be worth fixing anyways?

It's definitely not as pronounced in vanilla as it is in HackerSM64. Maybe it has something to do with like rounded corners or something?

Testing on my repo it seems that at times qstep doesn't see those steep slopes as valid floors

This I would assume is related to the collision changes with rounded corners, where it's probably assuming out of bounds earlier than it would otherwise with hitbox differences. Alternatively it could be related to some hitbox changes related to ceiling bonking and/or exposed ceilings. In either circumstance, I don't really know how to best circumvent the shell bonks here apart from making those two things configurable (which I already want anyway).
